Abstract

The present invention is concerned with a process for the preparation of sintered calcium aluminates that can generally be used as a protective cover for liquid metals, and particularly steel, and the process comprising the steps of mixing calcium oxide, or its precursor, particles and aluminum dross residue, such as NOVAL TM ; calcining the resulting mixture; maintaining a calcining temperature of 1200 DEG C. or higher for approximately 5 minutes or more which is sufficient to form a friable sintered product rich in calcium aluminates; and recovering the sintered product after cooling. Optionally, calcium fluoride, or other fluoride can be added to the starting mixture, if it is not already contained in the dross residue.
